Description
A047 Needle Plate Screw for GK9 Portable Bag Closer Machine
The A047 Needle Plate Screw is a precision replacement fastener designed to securely hold the needle plate (throat plate) on compatible GK9 Portable Bag Closer Machines. A firmly secured needle plate is essential for maintaining smooth fabric movement, consistent stitch formation, and safe machine operation during bag closing.
This replacement screw is manufactured with an industrial-grade countersunk head and precision thread to fit the original mounting position used in GK9 portable bag stitching machines. Once tightened, the screw sits flush with the needle plate surface, preventing bags from catching or snagging while passing through the sewing area.
Whether you are replacing a worn, damaged, or missing screw during machine maintenance, the A047 Needle Plate Screw helps restore proper machine performance with a secure factory-style fit.
Please verify Part Number A047 and compare the shape and thread of your existing screw before purchasing.

Why a Proper Needle Plate Screw Matters
Although small, the needle plate screw plays an important role in machine performance. It securely locks the needle plate to the machine frame, keeping the sewing surface stable while the feed mechanism moves the bag material.
A damaged, loose, or incorrect screw may cause:
- Needle plate movement
- Uneven feeding
- Increased vibration
- Needle strikes on the plate
- Difficulty maintaining stitch quality
- Premature wear of surrounding components
Replacing the screw with the correct A047 part helps restore stable machine operation.
Suitable Packaging Materials
While this component does not directly contact fabric, a securely fastened needle plate allows smooth movement of materials such as:
- Woven PP sacks
